    The 034Motorsport High Pressure Fuel Pump Piston Upgrade Kit for Audi 2.9T & 3.0T EA839 is erfinally here!

    The 034Motorsport High Pressure Fuel Pump Piston Upgrade Kit is designed to be a drop-in replacement piston for the factory high pressure fuel pump for the 2.9T and 3.0T TFSI EA839 engines found in the B9/B9.5 Audi S4/S5/SQ5/RS5, C8 Audi A6/A7/S6/S7, and 4M.5 Audi Q7/Q8.

    By upgrading the factory high pressure fuel pump with the 034Motorsport High Pressure Fuel Pump Piston Upgrade Kit, the factory fueling limits are raised by up to 37% in 2.9T or 3.0T EA839 engines.

    • Fuel Pump Internals Precision-Machined to Aerospace Tolerances
    • DLC Coated Piston and Cylinder for Reduced Friction and Increased Performance
    • Matched Piston and Cylinder for Absolute Precision
    • Relatively Easy Installation


    WHAT’S INCLUDED:

    In our testing, we found no indication that an upgraded spring was necessary.
